概要
For centuries, Euclid’s geometry seemed complete — a perfect system built from simple assumptions.
But one assumption always stood out: the parallel postulate.
Mathematicians struggled with it for generations. Some quietly explored what would happen if that assumption changed. When Bernhard Riemann finally asked the question openly, something surprising happened. Entirely new geometries appeared — coherent worlds where triangles don’t add up to 180 degrees.
The lesson reaches far beyond mathematics.
Throughout history, people have often mistaken familiar frameworks for ultimate truth. But mathematics reminds us that even the most elegant systems may rest on assumptions worth re-examining.
Today’s reflection considers the courage it takes to question certainty — and what might become possible when we do.
IntersectingUs is a short daily reflection exploring the intersection of mathematics, philosophy, and life.
